"Obviously our thoughts are with the Boozman family," said of the senator while at the event. "He's a terrific public servant for the state of Arkansas and I know on his mind right now is how fast can he get up out of that hospital bed and get back to the work that he enjoys doing and that's serving the great people of Arkansas."
